We have seen that usually, machine language programs are written in assembly language and are then translated into machine language. So, if we want to understand or debug a machine language program written by our company, we should look at the assembly language program used to generate it.
However, if this program wasn't written by our company and we don't have its assembly language source code available, it is useful to have a tool that tries its best to translate machine language programs into the corresponding assembly language programs. This tool, named a disassembler, cannot create an excellent assembly language program for the following reasons:
- No meaningful comments can be inserted into the code.
- Data variables have no symbolic name to make sense of them. They are just bytes of memory positions where some data is placed, and so they are referenced by their address.
- The destinations of jumps have no symbolic names to make sense of them. They...
